A quick learner from Tiburon says:

Hello and thank you for finding the replacement.
Couple of questions:
Do those vertical cut-outs make any difference?
What is the width of the roller wheels?

The vertical cuts won't make a difference. They are made so they can put in a flare on the housing. The ball bearing wheel is 1-1/4" in diameter and 5/16" wide.
